What if Storage Studio quits or crashes in the middle of moving an app?
Short answer: Moves are checkpointed. On the next launch Storage Studio finishes the move cleanly or returns the app to its original place with nothing missing.
Every move is checkpointed step by step. The next time Storage Studio launches, it looks at where the move stopped and either finishes it cleanly or returns the app to its original location with nothing missing. You don't need to do anything.
The same applies if your Mac loses power or you force-quit Storage Studio.
